This study was conducted to determine the effects of adding different levels of vetch seed (3%, 6%, and 9%) to apple pomace silages, which were prepared by equalizing the dry matter content with wheat straw, on silage quality, feed value, and rumen fermentation parameters. The in vitro gas production technique and Ankom Daisy in vitro fermentation system were used in the study. In the experiment, five silage groups were formed by adding apple pomace (control group), apple pomace + 10% wheat straw, apple pomace + 7% wheat straw + 3% vetch, apple pomace + 4% wheat straw + 6% vetch, and apple pomace + 1% wheat straw + 9% vetch. Each silage group was vacuum sealed in bags and fermented for 60 days. Analysis of the silage samples after fermentation revealed that NH3, Fleig score, NDF, ADF, gas production, true digestible dry matter, true digestibility, metabolic energy, net energy lactation, organic matter digestibility, dry matter digestibility, relative feed value, relative feed quality, partitioning factor, microbial gain, microbial protein synthesis efficiency, and individual volatile fatty acids, such as acetic acid and propionic acid, were significantly affected (P<0.05). It was also found that pH, crude fat, methane production, and methane percentage were not influenced by the treatments. As a result, it has been determined that the quality of silages created by increasing the dry matter content of apple pomace, which is a by-product of fruit industry processing, with wheat straw and adding vetch seeds at different rates, increases and provides positive effects on in vitro digestion values.
Bu çalışma, gruplar arasında kuru madde içeriği buğday samanı ile eşitlenerek hazırlanan elma posası silajlarına, farklı oranlarda fiğ tohumu (%3, 6 ve 9) ilavesinin; silaj kalitesi, yem değeri ve rumen fermantasyon parametreleri üzerine etkisini belirlemek amacıyla yapılmıştır. Çalışmada, in vitro gaz üretim tekniği ve Ankom Daisy in vitro fermantasyon sistemi kullanılmıştır. Denemede elma posası (kontrol grubu), elma posası+ %10 buğday samanı, elma posası+ %7 buğday samanı+ %3 fiğ, elma posası+ %4 buğday samanı+ %6 fiğ, elma posası+ %1 buğday samanı+ %9 fiğ ilave edilerek 5 silaj grubu oluşturulmuştur. Her bir silaj grubu 4 tekerrür olacak şekilde torbalarda vakumlanıp fermantasyon için 60 gün bekletilmiştir. Fermantasyon sonrası açılan silaj numunelerinde yapılan analizlerde NH3, fleig puanı, NDF, ADF, gaz üretimi, gerçek sindirilebilir kuru madde, gerçek sindirim derecesi, metabolik enerji, net enerji laktasyon, organik madde sindirim derecesi, kuru madde sindirilebilirliği, nispi yem değeri, nispi yem kalitesi, taksimat faktörü, mikrobiyal kazanım, mikrobiyal protein sentezleme etkinliği ve bireysel uçucu yağ asitlerinden asetik asit ile propiyonik asit değerlerinin önemli düzeyde etkilendiği belirlenmiştir (P<0.05). Gruplara ait pH, ham yağ, metan üretimi ve metan yüzdesi parametrelerinin muameleden etkilenmediği tespit edilmiştir. Sonuç olarak, meyve sanayi işleme yan ürünü olan elma posasının kuru madde içeriği buğday samanı ile artırılıp farklı oranlarda fiğ tohumu ilave edilmesi ile oluşturulan silajlarda kalitenin arttığı ve in vitro sindirim değerlerinde olumlu etkiler sağladığı tespit edilmiştir.
